What is the Systems Engineering? o Systems engineering consists of two significant disciplines: 1. The technical knowledge domain in which the systems engineer operates. 2. Systems engineering management. 06. 04. 2011 END 1202 - Technical English II 2

06. 04. 2011 END 1202 - Technical English II 3

o Three commonly used definitions of systems engineering are provided by the best known technical standards that apply to this subject. They all have a common theme: 1. A logical sequence of activities and decisions that transforms an operational need into a description of system performance parameters and a preferred system configuration. 06. 04. 2011 END 1202 - Technical English II 4

2. An interdisciplinary approach that encompasses the entire technical effort, and evolves into and verifies an integrated and life cycle balanced set of system people, products, and process solutions that satisfy customer needs. 3. An interdisciplinary, collaborative approach that derives, evolves, and verifies a life-cycle balanced system solution which satisfies customer expectations and meets public acceptability. 06. 04. 2011 END 1202 - Technical English II 5

o In summary, systems engineering is an interdisciplinary engineering management process that evolves and verifies an integrated, life-cycle balanced set of system solutions that satisfy customer needs. 06. 04. 2011 END 1202 - Technical English II 6

Systems Engineering combines element from many disciplines: 06. 04. 2011 END 1202 - Technical English II 7

Systems Engineering Management is… o Systems engineering management is accomplished by integrating three major activities: 1. Development phasing that controls the design process and provides baselines that coordinate design efforts, 2. A systems engineering process that provides a structure for solving design problems and tracking requirements flow through the design effort, 3. Life cycle integration that involves customers in the design process and ensures that the system developed is viable throughout its life. 06. 04. 2011 END 1202 - Technical English II 8

06. 04. 2011 END 1202 - Technical English II 9

The Systems Engineering Process is… o The systems engineering process is a topdown comprehensive, iterative and recursive problem solving process, applied sequentially through all stages of development, that is used to: 1. Transform needs and requirements into a set of system product and process descriptions (adding value and more detail with each level of development), 06. 04. 2011 END 1202 - Technical English II 10

The Systems Engineering Process is… 2. Generate information for decision makers, 3. Provide input for the next level of development. 06. 04. 2011 END 1202 - Technical English II 11

06. 04. 2011 END 1202 - Technical English II 12

The System Life Cycle o The System Life Cycle has seven phases: 1. Discovering system requirements, 2. Investigating alternatives, 3. Full-scale engineering design, 4. Implementation, 5. Integration and test, 6. Operation, maintenance and evaluation, 7. Retirement, disposal and replacement. 06. 04. 2011 END 1202 - Technical English II 13
